NETWORK PERFORMANCE ENHANCEMENT

摘要

Methods for overcoming latency and throughput degradation ensuing from packet fragmentation performed at a source node are disclosed. Some embodiments of the disclosed methods may be applicable to networks in which performance enhancement methods are used, including but not limited to TCP acceleration methods. In some embodiments, the disclosed methods may include determining an MTU for a session based on one or more fragmentation policies. Also disclosed is a satellite communication system that may be configured to resolve one or more detrimental effects on TCP spoofing resulting from the MTU discovery mechanism of IPv6.

主权项

1. A method, comprising:
receiving, by a second node, from a first node, and over a first link, a first packet associated with a session; storing, by the second node, a copy of the first packet associated with the session; transmitting, by the second node, toward a destination, and over a second link, the first packet associated with the session; responsive to transmitting the first packet associated with the session, receiving, by the second node, an indication that the first packet is too big and an indication of a maximum transmission unit associated with the second link; determining, by the second node, a new maximum transmission unit for the session; fragmenting, by the second node and in accordance with the new maximum transmission unit for the session, the first packet into a plurality of packets that comprise information from the first packet; and transmitting, by the second node, toward the destination, and over the second link, the plurality of packets that comprise information from the first packet.
